An upper portion of the case 110 may be opened to form an opening portion 111. The case 110 may be formed of synthetic resin.

The left/right hanging portion 120 may include a left hanging portion 121 and a right hanging portion 122 which are respectively formed at left and right inner surfaces of the case 110. As an example, the left hanging portion 121 and the right hanging portion 122 may be integrally formed when the case 110 is being formed by injection molding. As another example, not shown in the drawing, the left hanging portion 121 and the right hanging portion 122 may be coupled to the left and right inner surfaces by additional coupling members.

The first support rod 130 is a member for directly supporting a first wrap film roll 10, and is separably and rotatably supported on the left/right hanging portion 120, and the first wrap film roll 10 is fitted around an outer surface thereof.

The cover 140 is rotatably connected to the case 110 so as to open and close the opening portion 111. For example, the wrap film of the first wrap film roll 10 may be pulled out through a gap between the opening portion 111 and the cover 140.

The first cutter unit 150 may be provided at the front of the case 110 for cutting a wrap film which has been pulled out. Hereinafter, referring to FIG. 1 to FIG. 4, the first cutter unit 150 will be described in detail.

Hereinafter, parts different from the first embodiment will be explained.

The wrap film passing portion 210 is a place where the wrap film unwind from the third wrap film roll 30 is pulled out, and has a long slit shape which elongates along the length direction of the case 110 and is provided to a front surface of the case 110 with a first predetermined height gap from the opening portion 111.

The second left/right hooking portion 220 is a member where the second support rod 230 hangs, and includes a left hooking portion and a right hooking portion which are respectively provided to left and right inner surfaces of the case 110 with a second predetermined height gap from the first left/right hooking portion 120.

The second support rod 230 is a member where the third and the fourth wrap film rolls 30 and 40 are fitted and is separably connected to the second left/right hooking portion 220.

The second cutter unit 250 is a member for cutting the wrap film which has been pulled out through the wrap film passing portion 210, and is provided to a front surface of the case 110 with a third predetermined height gap from the first cutter unit 150. Meanwhile, since concrete structure of the second cutter unit 250 is equal to the first cutter unit 150, detailed description for the same will be omitted.

Further, the first, the second, and the third height gaps may be set as the same value so as to prevent confusion during design and manufacturing.

Further, the wrap case according to a second embodiment of the present invention has a double layers structure since the first and the second support rods 130 and 230 are disposed in parallel in a vertical direction, so the second support rod 230, which is disposed below the first support rod 130, may be difficult to be seen from a user. That is, remained amount of the third and the fourth wrap film rolls 30 and 40 which are fitted into the second support rod 230 may be difficult to be seen by a user. In order to solve this problem, a first seeing-through hole 112 may be formed at a position of the case 110 near the first left/right hooking portion 120, and a second seeing-through hole 113 may be formed at a position of the case 110 near the second left/right hooking portion 220. In particular, the first and the second seeing-through holes 112 and 113 may allow the remained amount of the wrap film rolls to be seen and at the same time play a role of a grip for lifting the wrap case. The first seeing-through hole 112 may also be applied to the first embodiment of the present invention.

Further, in order to prevent foreign substances from flowing into the case 110 through the first and the second seeing-through holes 112 and 113, seeing-through windows 114 which are made of transparent or semi-transparent material can be coupled respectively to the first and the second seeing-through holes 112 and 113. At this time, center portions of the seeing-through windows 114 may be formed to be concave so as to be grasped by hands of a user.

Meanwhile, the wrap case according to embodiments of the present invention may further include a slip prevention member 117 which is provided at a bottom surface of the case 110 and prevents the case 110 from slipping. For example, the slip prevention member 117 may be made of rubber and an embossed portion (not shown in the drawing) may be formed at a bottom surface thereof.

As such, the wrap case according to embodiments of the present invention has the following advantages.

According to embodiments of the present invention, since the circular blade 162 is rotatably connected to the support body 161, the entire portion of the knife blade 162 a formed at an outer periphery of the circular blade 162 can be evenly used so that it does not be easily blunt, compared to the blade (designated by reference numeral 44 in FIG. 4), so as to extend the lifespan of the circular blade 162.

Further, according to the embodiments of the present invention, since the moving cutter 152 can be removed from or connected to the cutter rail 151 through the mounting/dismounting unit 153, only the moving cutter 152 can be replaced when the lifespan of the circular blade 162 is run out, so the maintenance cost can be substantially reduced compared to the case that a new wrap case should be bought.

Further, according to the embodiments of the present invention, since only one case 110 is used, the manufacturing cost can be reduced when compared to the prior art in which an upper case (designated by reference numeral 14 in FIG. 15) and a lower case (designated by reference numeral 15 in FIG. 15) are separately formed.

Further, according to the embodiments of the present invention, since the support rod 130 is put on the left/right hooking portion 120, the structure and the assembling can be simplified when compared to the prior art in which multiple kinds of wrap film roll support means (designated by reference numeral 20 in FIG. 9) and a roll supporter (designated by reference numeral 30 in FIG. 9) are used.

Further, according to the second embodiment of the present invention, since a plurality of wrap film rolls having different sizes can be used by being arranged to be disposed in parallel in a vertical direction or in series in a horizontal direction, a cost can be reduced when compared to the prior art in which respective wrap cases should be bought for respective wrap film roll having different sizes and a space occupied by the wrap case can be reduced.

Further, according to the second embodiment of the present invention, since the seeing-through windows 114 are provided to the case 110, the currently remained amount of the wrap film can be easily observed, so extra wrap film roll can be prepared in good time.
